Muslim attackers have thrown rocks and broken glass at a Coptic Christian march in Cairo, injuring 10, witnesses told Reuters.

Marcher Hossam Victor says about 400 Christians marched through the Cairo neighborhood of Shubra Thursday to mark the end of 40 days of mourning after sectarian clashes that killed 27 people, most of them Christians.

During the march, attackers threw stones, bricks and broken glass on the marchers from a six-floor apartment building, Victor said. Clashes broke out and 10 people were injured, two of them seriously.

Victor said the attackers were supporters of ultraconservative Islamist candidates in Egypt's upcoming parliamentary elections.

Sectarian clashes have become more common since the uprising that ousted President Hosni Mubarak in February.

During the anti-Mubarak riots that marked the opening of the so-called Arab Spring in Egypt, the country's community of Coptic Christians came under attack by armed gangs of Islamists.

At least two Coptic churches were also burnt down during the uprising -- one with ten people inside. Additionally, on New Year’s Day a bombing in a Coptic church killed 21.

Cairo's caretaker junta has, to date, attempted to maintain the tolerant status quo of the Mubarak era, but Thursday's violence has raised concerns about the security of Egypt's Coptic Christians.

Islamists are expected to make significant gains in polls scheduled to begin on November 28.
